Title: Rotor construction for controlled-pole electric machines
Inventor: ROESEL JOHN F JR
IPC: H02K1/27
Filed: 2000-04-28
Granted: 2002-04-21
Abstract: A rotor for use in a high speed controlled-pole electric machine can include a rotor core having an exterior surface; a first layer of remagnetizable magnetic material positioned about the rotor core exterior surface; and a first layer of high strength fiber or wire binding the first layer of remagnetizable magnetic material to the rotor core exterior surface. The rotor can also have a additional layers of remagnetizable magnetic material disposed about the first layer of remagnetizable magnetic material and the rotor core and each bound to the rotor core by a its own layer of high strength wire. To resist significant centripetal force, the high strength wire and fiber layers should exhibit strength properties similar to common music wire having a tensile strength ranging from 225,000 PSI to over 400,000 PSI. Moreover, though the internal layers of high strength wire can have low coercive of magnetic properties, the outermost layer of high strength wire preferably comprises non-magnetic high strength wire. Each layer of remagnetizable magnetic material further comprises a plurality of magnetic blocks positioned adjacent to one another. Advantageously, each magnetic block can be slightly separated from each adjacent magnetic block. The slight separation can be calculated to allow for a thermal expansion of each magnetic block relative to the rotor core and adjacent magnetic blocks. Moreover, the magnetic properties of the magnetic blocks forming each layer can be specified individually for each layer to compensate for internal changes that can occur in externally applied magnetic fields due to the geometry of the rotor.

Title: Apparatus and method for queuing data
Inventor: SCHWARTZ STEVEN J
IPC: H04L12/56
Filed: 2000-06-29
Granted: 2002-08-11
Abstract: An apparatus and method for queuing data such as data being transferred across or within a switching node on a network are described. The queuing apparatus includes a plurality of inputs for receiving data to be transferred to at least one output, each input being adapted to receive data at a data rate associated with the input. Each input transfers data to a relatively short queue which stores the data received at the input. Each output is associated with as many short queues as their inputs capable of transferring data to the output. A long queue associated with the output receives data from each of the short queues associated with the output and forwards the data to the output. A control circuit associated with the output transfers data stored in all of the short queues associated with the output into the long queue. This transfer takes place at a data rate that is higher than the data rate associated with the input such that the short queues are prevented from becoming full. By implementing the queuing system in many short queues instead of fewer long queues, the overall system is more efficient and inexpensive to implement.

Title: Improved BiCMOS process with low temperature coefficient resistor (TCRL)
Inventor: HEMMENWAY DONALD
IPC: H01L21/3205
Filed: 2000-07-28
Granted: 2002-07-21
Abstract: A low temperature coefficient resistor (TCRL) has some unrepaired ion implant damage. The damaged portion raises the resistance and renders the resistor less sensitive to operating temperature fluctuations. A polysilicon thin film low temperature coefficient resistor and a method for the resistor's fabrication overcomes the coefficient of resistance problem of the prior art, while at the same time eliminating steps from the BiCMOS fabrication process, optimizing bipolar design tradeoffs, and improving passive device isolation. A low temperature coefficient of resistance resistor (TCRL) is formed on a layer of insulation, typically silicon dioxide or silicon nitride, the layer comprising polysilicon having a relatively high concentration of dopants of one or more species. An annealing process is used for the implanted resistor which is shorter than that for typical prior art implanted resistors, leaving some intentional unannealed damage in the resistor. The planned damage gives the TCRL a higher resistance without increasing its temperature coefficient. A process for fabrication of the resistor is used which combines separate spacer oxide depositions, provides buried layers having different diffusion coefficients, incorporates dual dielectric trench sidewalls that double as a polish stop, supplies a spacer structure that controls precisely the emitter-base dimension, and integrates bipolar and CMOS devices with negligible compromise to the features of either type.

Title: Non-constant speed phase clock device and method without digital buffer in scanner
Inventor: CHEN SHR-HUANG
IPC: H04N1/40
Filed: 2000-08-04
Granted: 2002-04-11
Abstract: A non-constant speed phase clock device and method without digital buffer in scanner are provided, wherein the present invention employs the characteristic of the shift register on the charged coupling device with the registers, and designs the application-specific integrated circuit to control the speed of phase clock, so as to directly communicate with the transmission interface, so as to achieve the purpose of not requiring the digital buffer for direct signal transmission function with the I/O interface. Because the present invention can eliminate the digital buffer in the conventional scanner, it can reduce the cost, remove the bandwidth limitation for the digital buffer, and further increase the transmission speed of the scanner and improve the overall performance of the scanner.

Title: Method for producing sub-micron granular aluminum-based composite material
Inventor: LIN CHING-BIN
IPC: C22C21/00
Filed: 2000-08-21
Granted: 2004-04-01
Abstract: A method for producing a sub-micron granular aluminum-based composite material comprises adding 0.05 mum sub-micron alumina particles into a 6061 aluminum alloy, and performing a hot forging casting operation to form a casting having three types of distribution of the alumina particles therein a type of distribution where the alumina particles are uniformly distributed therein, an agglomeration type of distribution where a wet aluminum alloy exists among the alumina particles, and an agglomeration type of distribution where alumina particles tightly bond together. A solid rotation friction method can be used to disperse the agglomerated alumina particles wetted by aluminum alloy through the plastic atom flow field generated by the friction process. The tightly agglomerated alumina particles will be separated due to the shearing force in the rotation process, and form an adhesion with the aluminum alloy base, and finally be embedded into the aluminum alloy by the forging operation, and be dispersed in the polishing crumbs through the plastic flow field. After the polishing crumbs are formed by the rotation friction process, the polishing crumbs and the molten 6061 aluminum alloy are uniformly mixed and cast to produce an aluminum-based composite material. Furthermore, the content of the reinforcing-phase particles in the composite material can be increased to increase the residual stress generated by the difference of thermal expansion coefficient between the reinforcing phase and the base material, the fineness of the crystals of the aluminum base caused by the reinforcing phase, and the dispersion strength of the alumina particles, thereby increasing the hardness thereof.

Title: Acoustic communication system
Inventor: BARTLETT DAVID
IPC: H04B11/00
Filed: 2001-02-21
Granted: 2003-02-01
Abstract: A toy system is described in which a data signal is encoded using spread spectrum technology to form a spread signal which is combined with an audio track to form a modified audio track. The modified audio track is then transmitted as an acoustic signal to a toy having an electro-acoustic transducer for converting the acoustic signal into an electrical signal which is then despread in order to regenerate the data signal, and the toy responds to the data signal. By using spread spectrum technology to spread the data signal over a wide frequency range, the spread signal in the modified audio track can be made virtually inaudible to a listener. The techniques described have relevance to acoustic communication systems other than toy systems.

Title: Method and apparatus for producing rectangular contact holes utilizing side lobe formation
Inventor: SCHROEDER UWE PAUL
IPC: G03F1/32
Filed: 2001-06-05
Granted: 2002-08-01
Abstract: An array of small square contact holes, on the order of magnitude of the exposing light wavelength, are formed by selecting the partial coherence and numerical aperture of the exposing light source and the pitch of the array of windows on an attenuating phase shifting mask so that side lobes formed by the exposing light being diffracted as it passes through the array of window constructively interfere with one another in the vicinity of a desired contact hole on the material surface. This constructive interference of side lobe patterns, in combination with the pattern formed by the light passing undiffracted through the array of windows, forms an array of square exposed regions on the material surface. When the material is a photoresist, the exposed regions can be selectively dissolved in order to form square patterns that can be used to etch square holes in the underlying substrate or layer. In subsequent steps, selected ones of the array of square holes can be filled in with a conductive material to form vias and selected others of the square holes can be filled in with an insulating material so as to avoid the formation of unintended vias or conducting paths.

Title: Multi-generator, partial array Vt tracking system to improve array retention time
Inventor: ELLIS WAYNE F
IPC: G11C8/08
Filed: 2001-05-25
Granted: 2002-11-11
Abstract: Improved transistor array device performance is obtained by use of bias voltage regulation which tracks with a fraction of a monitor transistor threshold voltage. The circuitry and methods are especially useful for improving the performance of transistor array devices such as DRAM and embedded DRAM. These benefits are obtained especially when at least two bias voltages normally supplied to the array are regulated by tracking with a fraction of an actual threshold voltage of at least one monitor transistor. Performance improvements include improved reliability, winder operational bias conditions, reduced power consumption and (in the case of memory cells) improved retention time.
